Given:
Number of blue marbles = 6
Number of red marbles = 4
Number of green marbles = 4
Choose one marble without looking,
To find:
The probability that the selected marble is red or green.
Solution:
For the given problem,
Total outcomes = Total number of marbles
=
=
Favorable outcomes = Number of red or green marbles.
=
=
The probability that the selected marble is red or green, is
Therefore, the probability that the selected marble is red or green, is .
4.85 ÷ 4.5=1.08
Step-by-step explanation:
The initial question is;
4.86 ÷ 0.45 = 10.8
The question is ;
4.85 ÷ 4.5=?
You notice the numerator value does change with a small margin of 0.01 that you can neglect.The denominator however changes by a factor of 10, thus the answer should be multiplied by a factor of 1 tenth.This means, without calculation,
4.85 ÷ 4.5=1.08

Multiply the values of a and c together;
9*30= 270 <— find prime factors of this
270= 3*3*3*5*2
Now find a way to add these factors in different ways to give 33 (b value)
We can try (3*3*2)+(3*5)=?
18+15=33
Now that you know the numbers, break down the b value.
9x^2+18x+15x+30
9x(x+2)+15(x+2) <— make sure the brackets are the same
(9x+15)(x+2) <— check if this expands to the initial answer

Answer:
20,000
Step-by-step explanation:
We can create a proportion to find the total budget. A proportion is an equation where two ratios are set equal to each other. We create two fractions using the budget and percents.
We begin solving by cross multiplying numerator to denominator of each fraction.
